Choosing between two big closed cell spray foam kits can feel like comparing units that don't line up: one is listed in square feet, the other in board feet. If you're sorting out insulation drywall ceiling systems, the real decision is whether you want a 48-can fire-rated kit with a 960 Sq Ft coverage figure or a 36-can soundproofing kit with a 240 Bd Ft figure and a lower listed price.
Quick verdict: Go with the Akfix Closed Cell Expanding Spray Foam Insulation Kit (Fire Rated, 960 Sq Ft, 48 Pk) if you want the fuller kit. Choose the Spray Foam Insulation Kit Closed Cell Self Expanding Foam (240 Bd Ft, 36×32.8 oz) when a more compact kit fits the job.

Akfix Closed Cell Expanding Spray Foam Insulation Kit (Fire Rated, 960 Sq Ft, 48 Pk)
The Akfix kit includes 48 cans of 27.1 oz fire-rated closed cell spray foam, one professional spray foam gun, foam cleaner, a coverall, safety goggles, protective gloves, and a protective mask. Its listed compatible surfaces include concrete, drywall, metal, plywood, PVC, and wood, giving you a straightforward fit for ceiling and wall cavities. The fire-rated description and water-resistant attribute are the strongest reasons to choose it for a larger air-sealing job. The limitation is the higher listed price at USD 519.99: you're paying for 48 cans and the included gear, so the upfront cost is harder to justify for a small application.
Spray Foam Insulation Kit Closed Cell Self Expanding Foam (240 Bd Ft, 36×32.8 oz)
The Adhesive Guru kit brings 36 cans of 32.8 oz self-expanding closed cell foam, a dispensing gun, 36 blue and 36 black nozzles, foam gun cleaner, gloves, two masks, two coveralls, and safety glasses. The attributes highlight soundproofing insulation and an Insulation R-Value of R55, making it a reasonable fit for adding acoustic resistance while sealing gaps around ceilings and walls. The concrete and metal surface listing, plus the description's mention of wood, drywall, stone, and glass, points to versatile application. The limitation is the smaller listed coverage of 240 Bd Ft and the 36-can count when measured against the Akfix kit's larger coverage.
Final choice by use case
For a broad insulation run where the fuller kit makes sense, choose the Akfix option. For a contained project where the more compact kit fits, choose the Adhesive Guru option.
